Cotton fabric capable of isolating and killing virus and bacteria and its making process and use

Abstract

The making process includes mixing nano carbon material and volatile solvent to compound solution with dispersed nano carbon material of 3-50 g in each liter, soaking cotton gauze in the solution or brushing the solution to the cotton gauze, and drying to obtain the cotton fabric. The cotton fabric has virus and bacteria killing function greatly higher than that of other active carbon material.The present invention adopts fibrous carbon nano material, which is twisted to cotton fabric and has great adhesion, high durability and other advantages compared with granular carbon nano material and other kind of carbon nano material.

Description

technical field [0001] The invention relates to a cotton fabric for isolating and killing viruses and / or bacteria, especially suitable for isolating and killing severe viruses and bacteria. Background technique [0002] At present, ordinary medical masks generally only play the role of isolating dust, bacteria and viruses, but do not kill bacteria or viruses, and their filtering effect is poor. According to different requirements, it is generally made into several layers or more than ten layers. However, as the thickness increases, its wearing comfort decreases, which is not conducive to long-term wearing. At present, masks made of activated carbon materials have appeared on the market. Its main function is to use the strong adsorption of activated carbon to achieve the effect of killing bacteria and viruses. The price is about twice that of ordinary masks, and it is hard and comfortable to wear. Sex is poor. [0003] For severe viruses or bacteria (such as SARS virus), me...
